Ananthanarayanan was awarded the Royal Microscopical Society Life Sciences Award in 2025 for the use of novel microscopies in cell biology. Her group images individual motor proteins — dynein, kinesin — and the mitochondria they transport, in living cells, at single-molecule sensitivity, combining light-sheet and TIRF-class imaging with particle tracking to ask how organelle positioning and mitochondrial dynamics are controlled. The methodological emphasis is on getting single-molecule sensitivity inside a live cell rather than in vitro, which is the hard version of the problem. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — this is the closest thing at UNSW to a biological end-user for an in-cell quantum sensor: the mitochondrial systems she studies are precisely where NV nanodiamond thermometry and free-radical relaxometry at pT/sqrt(Hz) have been aimed, and she has the live-cell imaging infrastructure to validate any such measurement independently.
Mulvaney directs the ARC Centre of Excellence in Exciton Science and runs Melbourne's nanoscience laboratory. The group's distinctive capability is single-particle and single-emitter optical spectroscopy: photon-antibunching and blinking statistics from individual quantum dots and perovskite nanocrystals, photothermal and dark-field spectroscopy of individual metal nanoparticles, and the electrochemical control of single-nanocrystal charge state. Applications run from LEDs and solar cells to quantum-dot probes for single-particle tracking in cells. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his single-emitter photon-statistics measurements share the shot-noise-limited photon-counting methodology of NV-ensemble ODMR readout, and the group's nanocrystal probes are direct competitors/complements to nanodiamond in cellular sensing. Large, well-resourced group.
Reece runs UNSW's optical trapping and nanophotonics laboratory. The group combines optical tweezers with spectroscopy and microfluidics to characterise individual nanoparticles and cells: trapping and spectroscopically interrogating plasmonic core-satellite assemblies (with Gooding and Tilley), measuring single-cell mechanics, and building porous-silicon and photonic-crystal resonant structures for label-free biosensing where the analyte shifts a cavity resonance. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — optical trapping is the standard way to hold a nanoscale sensor — including a nanodiamond hosting an NV ensemble at pT/sqrt(Hz) — at a controlled position inside a cell or fluid, and levitated-nanodiamond spin-mechanics is an active field that this group's capabilities map onto almost exactly. Strong practical fit for a bio-oriented quantum sensing candidate.
Yang's experimental physical chemistry lab designs new instrumentation to track single proteins, nanoparticles, and other emitters in three dimensions in real time within complex, heterogeneous environments, including a recent time-gated two-photon platform for high-speed 3D single-particle tracking. His group applies these single-molecule tracking and orientation-resolved imaging tools to protein conformational dynamics, functional nanostructures, and active-matter systems.
